how do I draw a filled polygon on a line data series chart?

[ian dean]

I need to add a polygon to a data series in mschart.
I have tried the following:-
...using Systems.Windows .Forms;
...
formGraphics.Fi llPolygon(myBru sh,MyCurve);

{this works OK but on a plain form with no axes)


...

chart1.Series[0].Points.AddXY(1 .0, 2.0);
...
chart1.Series[0].Points.AddXY(5 .0, 20.0);
...
formGraphics.Fi llPolygon(MyBru sh, MyCurve));

>>> This draws the series on a graph but no polygon.


using Systems.Windows .Forms.DataVisu alization.Chart ing;

ChartGraphics.F illPolygon(MyBr ush, MyCurve);
>>> this complains that ...FillPolygon is inaccessible due to its protection level
